jit.anim.node – off-center rotation

I have a jit.gl.sketch with a red cube at the origin, and a blue cube offset from it. By using a jit.anim.node, I can easily make the blue cube rotate around the red cube. But how would I make the red cube rotate around the blue cube? In other words, how would I set up a rotation around a pivot point that isn’t at the center of an object?
